Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# 37signals Skills Repo

Publish target for the agent skills of 37signals products: Basecamp, HEY, and
Fizzy. Each product's CLI mirrors its `skills/` tree into `skills/` here on
release, via that CLI's `scripts/sync-skills.sh`. Nothing under `skills/` is
written by hand.

For installation, see [install.md](install.md).

## Sources

| Source | Skills | Publishes here |
|--------|--------|----------------|
| [basecamp-cli](https://github.com/basecamp/basecamp-cli/tree/main/skills) | `basecamp`, `basecamp-doctor` | On each stable release |
| [hey-cli](https://github.com/basecamp/hey-cli/tree/main/skills) | `hey` | On each stable release. Absent right now: see [#5](https://github.com/basecamp/skills/issues/5) |
| [fizzy-cli](https://github.com/basecamp/fizzy-cli/tree/master/skills) | `fizzy` | Not yet; a release sync is proposed in [fizzy-cli#214](https://github.com/basecamp/fizzy-cli/pull/214) |

## Key constraints

- **Do not edit skills here.** Edit them in the CLI repo that owns them
  (`basecamp-cli/skills/`, `hey-cli/skills/`, `fizzy-cli/skills/`) and let the
  next release publish them. Manual edits here are overwritten by that release.

How to install

The exact contents, by fingerprint
mdr add basecamp/skills/AGENTS.md@sha256:31208a341c93918a

The line at the top of this page pins the label git:20260914.0cd0a04, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
